use heated water which -is ordinarily con ducted away in waste pipes.

I have designed my invention for use 1n cooling the condenserwater from ice-making machines, but it is evident that it may be employed for cooling `iuid derived from any source and designed for any purpose.

Referring to the accompanying drawings, Figure 1 is an elevation of one form' of my invention with portions vbroken away to show the internal structure; Fig. 2, a plan thereof with a portion broken away; Fig. 3, a vertical section of a portion of my invention showing a modification of the fan-Casing "and `attachments; Fig. 4C, a perspective of one end of a plate-holding cooling frame; Fig. 5, a cross-section of a 4plate-holding frame with the cooling plates thereon; and Fig'. 6, a perspective of one of the said cooling plates. y

vOn the drawings, 1 designates a ,rectangular box, having across the lower portion of one end the opening 2, around which I secure the sprayer-casing 3 having its outer end open and provided with a number of sprayer nozzles t projecting into the same.

In the top of the box 1, I place the hotwater receptacle 5 having its top open and its bottom provided ,with numerous holes, in which I place sprayer, or discharge tubes G, provided preferably with regulating valves 7. As shown the tips of the spraying tubes have contracted nozzles to cause the water to issue with suiiicient force to form sprays.

Within the box 1 below the receptacle 5, I place cooling frames 8 arranged in several horizontal groups arranged one over the other, as clearly shown on Fig. 1. Each frame consists of a framework covered with the perforated cooling plates 9; Each framework is preferably constructed as follows: A. wooden plate or support 10 having its sides tapering upwardly has secured Y Specification of Letters Patent.

thereto, the oppositely arranged pairsl of supports'or pieces 11, the members of. each Vpair diverging downwardly. To the lower of the plates are supported on the cleats 14 secured to the interior faces of the sides of the box 1. To the sides of each framework, I secure the metal plates 9. which ha ve horizontal rows of tongues 15 stamped there.-

from, the 'holes' in consecutive rows being staggered. The tongues remain attached to the plates at their upper ends and project outwardly away from' the framework ,so as to form sloping shelves upon which the water from the receptacle 5 Hows. The

frames are arranged in tiers or groups, each" group consisting of a series of parallel frames.' The frames inconsecutive groups are arranged at right angles as shown on 'Fig'. l1 yto y.cause a greater subdivision of the falling water and to break up any direct routes of travel of air from the casing 3 to the fan-casing, soon to be described. At the upper portion of the side opposite the casing 3, I place the fan-.casing 16 resting on the trestle 17. The fan-casing draws air from the box 1 through the opening 18 opposite the upper groups of frames, preferably as shown on Fig. 1. From the fan-casing the air is blown through the pipe 19 which opens downwardly over the receptacle 5, so that any water carried along with the air will be deflected back into the receptacle.

The receptacle having been supplied with hotfor warm water, the pipes 6 having been opened, andthe fan having been set in operation, air is drawn into the casing 3 and Y charged with moisture from the 'spray pipes 4. From the casing 3 the moisture-laden air is drawn into the box `1 through and around the cooling frames and through the water falling from the receptacle 5. FromV the box 1 the air passes through the opening 18 into the fan-casing 16, from which it is .driven .through the'pipe 19, whose downwardly turned outerl end-deflects any water in the air into the receptacle 5. As the air passes through the casing 8 it israreied and caused to expand, causing the absorption of 'considerable thevapor dragged along 19. The cooling 'of the spray from the spayeijsfia The expansion of the air and the water issuing from the spray pipes 4 reduces the temperature of both materially before the mlsty spray resulting from the lmixture of the air yand 'water entersthe box 1. The rarefaction. of the air and vapor continues in the box 1 where the cooled air from the casing 3 meets the metal of the frames and cools them and also meets the falling inely subdivided water or spray from the pipes 6 and directly cools it. The water in the form of spray and the water condensed from the spray coming in contact with the' plates 9 imparts a large part of their heat thereto, which -is carried ott by the fan and discharged through the pipe om the receptacle 5 is caused directly by contact withv .the rareed cooled air and also indirectly by the air which cools the plates 9. v

In Fig. 3, I show a fan casing 16a which may be of wood'. Within the casing'la is the fan 16? which draws the air from the box 1 and discharges it into the said casing,

. which has a portion overhanging the receptacle 5 and having its bottom open. In the upper part of t-he casing 16a is an inclined de'ilector 20 arranged to direct any water swept along with the air into the yreceptacle 5.I

It will be understood that the raretied condition of the air in the box .1 will assist gravitation iu forcing the Water through `the pipes 6 and thus' increase the ineness of the subdivision of the sprays therefrom.

I provide the door 21 whereby access may 4be had to t-he interior` of the box below the pipes 6 for repairs or other purposes. 1
